Description

Technical Field

[0001] This utility model relates to the field of ultrasonic flow meter technology, specifically to an ultrasonic flow meter for real-time temperature detection. Background Technology

[0002] In the field of fluid measurement, ultrasonic flow meters have been widely used due to their advantages such as non-contact operation and no pressure loss.

[0003] Existing ultrasonic flow meters typically detect fluid flow rate using ultrasonic transducers. However, in practical applications, the propagation speed of ultrasound in a fluid is closely related to the fluid temperature. Temperature changes can cause significant fluctuations in the speed of sound, and since the fluid temperature is not constant, these temperature-induced changes in the speed of sound directly introduce flow rate measurement errors, becoming a factor affecting the accuracy and stability of ultrasonic flow meter measurements.

[0004] To overcome the aforementioned problems, existing ultrasonic flow meters typically require an additional independent temperature sensor and instrument, with post-compensation correction achieved through external temperature measurement. This approach not only increases system complexity and equipment procurement costs but also potentially introduces new errors due to the separation of the temperature measurement point from the flow measurement section. Furthermore, it makes installation and wiring more cumbersome and cannot guarantee the accuracy of fluid flow measurement results. Utility Model Content

[0005] Given that existing technologies increase system complexity and equipment procurement costs, and may introduce new errors due to the separation of temperature measurement points and flow measurement sections, thus failing to guarantee the accuracy of fluid flow measurement results, this utility model provides an ultrasonic flow meter for real-time temperature detection. By integrating a temperature measurement mechanism into the measurement pipe section, it achieves efficient synchronous measurement of flow and temperature, effectively realizing multiple uses with a single meter. This not only eliminates the need for additional temperature instruments, simplifying system configuration and saving equipment costs, but also reduces structural complexity and significantly improves the overall measurement integration and reliability.

[0006] This utility model provides an ultrasonic flow meter for real-time temperature detection, comprising: a measuring pipe section, an ultrasonic mounting mechanism symmetrically arranged on both sides of the measuring pipe section, and a temperature measuring mechanism disposed on the measuring pipe section.

[0007] The temperature measuring mechanism includes: a temperature measuring hole opened on the measuring pipe section, and a temperature measuring element inserted into the measuring pipe section through the temperature measuring hole.

[0008] The ultrasonic mounting mechanism includes: a mounting base mounted on the measuring tube section, a transducer mounting hole provided on the mounting base, a detachable ultrasonic transducer inserted into the transducer mounting hole, a limiting member provided on the outside of the ultrasonic transducer, and an outer shell cover provided on the outside of the mounting base.

[0009] Furthermore, the temperature measuring hole is located below the measuring tube section, and the temperature measuring element and the temperature measuring hole are installed with a threaded seal.

[0010] Furthermore, the temperature measuring element is a temperature sensor.

[0011] Furthermore, the ultrasonic transducer includes: a mounting base installed in the transducer mounting hole and an ultrasonic transducer installed on the mounting base, wherein the outer wall of the mounting base is provided with mounting protrusions.

[0012] Furthermore, the inner wall of the transducer mounting hole is provided with a mounting groove that mates with the mounting protrusion.

[0013] Furthermore, the acoustic end face of the ultrasonic transducer extends into the cavity of the measuring tube section, and the acoustic end faces of the ultrasonic transducers installed in the two ultrasonic mounting mechanisms are alternately arranged opposite each other.

[0014] Furthermore, the mounting base and the measuring tube section are integrally formed, and the limiting member is threadedly fitted with the transducer mounting hole.

[0015] Furthermore, the upper side wall of the inner cavity of the mounting base is provided with a through hole for the data transmission line to pass through.

[0016] Furthermore, a flow meter head for reading measurement data is installed on the measuring pipe section, and the data transmission line of the ultrasonic transducer passes through the wire hole and is connected to the flow meter head.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model patent achieves efficient synchronous measurement of flow rate and temperature by integrating a temperature measuring mechanism into the measuring pipe section. The temperature measuring element extends directly into the measuring pipe section through a temperature measuring hole, making full contact with the fluid, thereby quickly and accurately capturing the real-time temperature. This structure not only monitors the temperature in real time, but also comprehensively judges the actual flow velocity of the fluid in the measuring pipe section through real-time temperature monitoring, effectively eliminating the influence of sound velocity fluctuations caused by fluid temperature changes on the flow velocity measurement results, and improving the accuracy and stability of flow velocity measurement. At the same time, it enables the ultrasonic flow meter to have dual parameter output functions of flow rate and temperature, effectively realizing multiple uses with one meter. This not only eliminates the installation of additional temperature instruments, simplifies system configuration, saves equipment costs, but also reduces structural complexity, significantly improving the overall measurement integration and reliability.

[0019] 2. This utility model patent allows the ultrasonic transducer to be detachably installed in the transducer mounting hole. The ultrasonic transducer is fixed by a limiting component. The cooperation between the mounting protrusion and the groove ensures the accurate and firm positioning of the ultrasonic transducer's acoustic end face, further improving the convenience of daily maintenance, replacement or calibration operations. That is, there is no need to disassemble the entire measuring tube section or the mounting base, reducing maintenance costs and time.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly set on the other component; when a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] Please refer to Figures 1-6 This utility model provides an ultrasonic flow meter for real-time temperature detection, including: a measuring pipe section 1, an ultrasonic mounting mechanism 2 symmetrically arranged on both sides of the measuring pipe section, and a temperature measuring mechanism 3 arranged on the measuring pipe section 1.

[0033] The temperature measuring mechanism 3 includes: a temperature measuring hole 31 opened on the measuring tube section 1, and a temperature measuring element 32 inserted into the measuring tube section 1 through the temperature measuring hole 31.

[0034] The ultrasonic mounting mechanism 2 includes: a mounting base 21 mounted on the measuring tube section 1, a transducer mounting hole 22 provided on the mounting base 21, a detachable ultrasonic transducer 23 inserted into the transducer mounting hole 22, a limiting member 24 provided on the outside of the ultrasonic transducer 23, and an outer shell cover 25 covering the outside of the mounting base 21.

[0035] This embodiment achieves efficient synchronous measurement of flow rate and temperature by integrating a temperature measuring mechanism 3 into the measuring pipe section 1. The temperature measuring element 32 extends directly into the interior of the measuring pipe section 1 through the temperature measuring hole 31, making full contact with the fluid, thereby quickly and accurately capturing the real-time temperature. This structure not only monitors the temperature in real time, but also comprehensively judges the actual flow rate of the fluid in the measuring pipe section 1 through real-time temperature monitoring, effectively eliminating the influence of sound velocity fluctuations caused by fluid temperature changes on the flow rate measurement results, and improving the accuracy and stability of flow rate measurement. At the same time, it enables the ultrasonic flow meter to have dual parameter output functions of flow rate and temperature, effectively realizing multiple uses of one meter. This not only eliminates the installation of additional temperature instruments, simplifies system configuration, saves equipment costs, but also reduces structural complexity and significantly improves the overall measurement integration and reliability.

[0036] Furthermore, in this embodiment, the ultrasonic transducer 232 is detachably installed in the transducer mounting hole 22, and the ultrasonic transducer 232 is fixed by the limiting member 24. The precise and firm positioning of the ultrasonic transducer 232 acoustic end face is ensured by the cooperation of the mounting protrusion 233 and the groove, which further improves the convenience of daily maintenance, replacement or calibration operations. That is, it is not necessary to disassemble the entire measuring tube section 1 or the mounting base 21, reducing maintenance costs and time.

[0037] To further clarify, the temperature measuring hole 31 is located below the measuring tube section 1, and the temperature measuring element 32 and the temperature measuring hole 31 are installed with a threaded seal.

[0038] In this embodiment, the temperature sensing end of the temperature sensing element 32 is screwed into the temperature sensing hole 31 via a thread and extends deep into the measuring pipe section 1, making full contact with the fluid to achieve real-time, continuous, and accurate temperature monitoring. Simultaneously, the ultrasonic transducers within the ultrasonic mounting mechanisms 2 on both sides work in tandem, emitting ultrasonic waves on one side and receiving signals on the other, to detect the fluid velocity and flow rate in real time. This structure ensures that the temperature sensing section and the velocity sensing section are located in the same fluid region, guaranteeing the consistency of the measurement area. This effectively compensates for the influence of temperature on sound velocity, eliminates flow rate measurement deviations caused by temperature fluctuations, and allows the ultrasonic flow meter to integrate and read accurate fluid temperature and flow rate values, improving data synchronization and significantly enhancing the accuracy and reliability of the overall measurement.

[0039] like Figure 3 and Figure 6 As shown, the ultrasonic transducer 23 includes: a mounting base 231 installed in the transducer mounting hole 22 and an ultrasonic transducer 232 installed on the mounting base 231. The outer wall of the mounting base 231 is provided with mounting protrusions 233.

[0040] Furthermore, the inner wall of the transducer mounting hole 22 is provided with a mounting groove 221 that mates with the mounting protrusion 233.

[0041] In this embodiment, the ultrasonic transducer 232 is securely installed via the mounting base 231, facilitating rapid response in case of damage to the acoustic end face of the ultrasonic transducer 232 or other sudden malfunctions. When replacement is required, the ultrasonic transducer 232 can be removed as a whole for quick replacement, significantly improving maintenance efficiency. Furthermore, the mating insertion method of the mounting protrusion 233 and the mounting groove 221 ensures that the ultrasonic transducer 23 can be accurately inserted into the transducer mounting hole 22 at a defined angle, effectively preventing misalignment or deflection. This not only simplifies the installation process but also ensures the directionality and accuracy of ultrasonic signal reception, thereby guaranteeing the reliability of the detection process and the accuracy of the data.

[0042] like Figure 1 and Figure 5As shown, the mounting base 21 and the measuring tube section 1 are integrally formed, and the limiting member 24 is threadedly fitted with the transducer mounting hole 22.

[0043] In this embodiment, the ultrasonic transducer 23 is inserted into the transducer mounting hole 22, and the limiting member 24 is disposed on the outside of the ultrasonic transducer 23. Through the threaded engagement between the limiting member 24 and the transducer mounting hole 22, the ultrasonic transducer 23 is effectively and tightly fixed, which enhances the mechanical stability of the transducer under complex working conditions and further ensures the stability of the ultrasonic transducer 232 when transmitting or receiving ultrasonic signals, thereby significantly improving the consistency and reliability of ultrasonic signal transmission.

[0044] To further explain, the outer cover 25 is connected to the mounting base 21 by several screws. When the ultrasonic transducer 23 needs to be replaced, the outer cover 25 is removed from the mounting base 21 by unscrewing several screws. Then, the limiting member 24 is unscrewed to remove it from the transducer mounting hole 22. At this time, the ultrasonic transducer 23 can be removed from the transducer mounting hole 22 and replaced with a new ultrasonic transducer 23. Then, the limiting member 24 is screwed back into the transducer mounting hole 22 to securely install the new ultrasonic transducer 23. Finally, the outer cover 25 is installed on the mounting base 21 by several screws to complete the replacement of the ultrasonic transducer 23.

[0045] Furthermore, the temperature sensing element 32 is a temperature sensor, which can provide the ultrasonic flow meter with real-time and accurate temperature signals, thereby directly ensuring the high accuracy of the final flow measurement. It realizes real-time temperature monitoring and digital processing, and has a faster response speed than the mechanical temperature sensing element 32, further ensuring the accuracy of the data.

[0046] like Figure 2 The acoustic end face of the ultrasonic transducer 232 extends into the cavity of the measuring tube section 1, and the acoustic end faces of the ultrasonic transducers 232 installed in the two ultrasonic mounting mechanisms 2 are alternately arranged opposite each other.

[0047] In this embodiment, the ultrasonic transducer 232 has a bidirectional function, serving as both a transmitter and a receiver of ultrasonic waves. Its acoustic end face is an inclined, opposing structure, allowing the ultrasonic transducers 232 mounted on different ultrasonic mounting mechanisms 2 to achieve precise cross-oblique alignment of their acoustic end faces. Furthermore, when measuring the fluid velocity and flow rate within the measuring pipe section 1, a group of obliquely opposing ultrasonic transducers 232 act as both transmitters and receivers, working together to ensure the accuracy of the detection operation.

[0048] Furthermore, the obliquely opposite arrangement of the ultrasonic transducers 232, located within different ultrasonic mounting mechanisms 2, effectively enhances the propagation efficiency of ultrasonic waves in the fluid, significantly improving signal strength and stability. Simultaneously, because the ultrasonic waves penetrate the fluid via an oblique path, their propagation distance within the measured fluid is significantly increased, making them more sensitive to changes in fluid velocity and improving measurement accuracy and response capability.

[0049] like Figure 4 and Figure 5 As shown, the upper side wall of the inner cavity of the mounting base 21 is provided with a wire hole 4 for the data transmission line to pass through.

[0050] To further explain, a flow meter head 5 for reading measurement data is installed on the measuring pipe section 1, and the data transmission line of the ultrasonic transducer 232 passes through the wire hole 4 and is connected to the flow meter head 5.

[0051] In this embodiment, the wiring hole 4 allows the data collected by the ultrasonic transducer to be stably transmitted to the flow meter head 5 via the data transmission line. The flow meter head 5 rapidly processes and analyzes the signal, ultimately displaying key information such as flow velocity clearly and accurately on the screen. At this point, the inspector can accurately and clearly read the flow velocity value displayed on the flow meter head 5. Furthermore, the real-time fluid temperature data collected by the temperature sensing element 32 is also transmitted to the flow meter head 5, and the analyzed and processed fluid temperature data is simultaneously read on the screen, further improving the convenience and reliability of on-site testing.

[0052] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
